Anthropic has gone from making plug-ins for Office to launching its own spreadsheets and whiteboards. Officials admit that it is still in beta and its functions need to be optimized, but it has a strong intention to replace Microsoft Office applications. (Preliminary news: Anthropic launches Claude Docs and Slides: files and presentations can be edited instantly and collaborated in the cloud) (Background supplement: Anthropic’s IPO target valuation is about US$1 trillion! The code name ANT is expected to start trading next week) This time Anthropic launched two new features on 11/10: Claude Sheets (spreadsheets) and Claude Whiteboards (whiteboards), both beta test versions. According to the official blog, users of all paid plans can use it. Another one, Claude Meetings (a conference assistant that allows Claude to join the call and take notes), is only officially announced as "coming soon" and is not available yet. Sheets Just describe your needs in one sentence, such as "make a marketing activity tracking sheet", and Claude will generate a spreadsheet with pagination, formulas and drop-down menus, modify it directly in the storage grid, and mark each change. Whiteboards organizes the messy plans you verbalize into a timeline with responsible persons and dates. Both can be shared with colleagues for modification together. In addition, in October, a beta version of the function was first launched in the name of Dashboards. This time it was converted to the official version and renamed Claude Data, allowing employees to directly ask questions about company information. Could this replace Excel? The official blog states that Sheets currently only has a simple spreadsheet function and is still being supplemented; when you need the full functionality of Excel, you can export the file to .xlsx or CSV, or use Claude for Excel (Excel plug-in) instead. Product leader Nicholas Lin told Bloomberg that Sheets is currently very young and is not used for advanced financial models. For complex work, it is more suitable to use a plug-in connected to the existing spreadsheet software. Why do you say it's directed at Microsoft? Because Anthropic’s approach has changed. In the past, it was a plug-in that "goes into Office", including Word, Excel, and PowerPoint; now it even makes the spreadsheet itself. The officially emphasized selling point is also here: Claude carries the same context at every step, and ideas can be taken from the whiteboard to the spreadsheet to the data dashboard without having to explain it again. The market seems to be responding as well. The closing price showed that Microsoft closed down 2.20% on 11/10, and fell about 3.4% at one point during the session; Google only fell 0.27% on the same day, and QQQ, which tracks the Nasdaq 100 Index, fell 0.68%. Microsoft's decline was obviously heavier than the broader market, but there are many factors involved in a single day's stock price, and not all of them can be counted on this announcement. But Microsoft's role is a bit more nuanced: It's also a shareholder in Anthropic. The prospectus submitted on the eve of the IPO stated that Microsoft would buy approximately US$1 billion in shares at the issue price in a private placement concurrent with the IPO. I also wrote the risk section of the prospectus myself. Amazon, Google, and Microsoft are both investors and customers of Anthropic, and they are each making products that compete with Anthropic.

Claude officially supports modifying Word files and saving workflows as skills, and the three-piece integration of Microsoft Office is completed. Microsoft predicts that the Copilot super App will be launched this year, and the financial report is better than expected, soaring more than 8% after the market.
